High-dose Use of rhTPO in CIT Patients (HUrhTPOCITP)

October 28, 2018 updated by: First Affiliated Hospital Xi'an Jiaotong University

High-dose Use of Recombinant Human Thrombopoietin in Patients With Moderate or Severe Thrombocytopenia Induced by Chemotherapy

The research studies the safety and efficacy of high-dose recombinant human TPO in solid tumor patients with moderate or severe thrombocytopenia induced by chemotherapy. Patients with platelet count lower than 50 x 109/L will be enrolled and treated with high-dose rhTPO (300-600U/kg/day) until the platelets increased by 50 x 109/L compared to the baseline or above 100 x 109/L. During the study, the blood routine test will be regularly performed according to the clinical routine (at least once every two days). Finally, the clinical data will be collected and analyzed to validate the efficacy and safety of high-dose rhTPO therapy.

Detailed Description

Chemotherapy-induced thrombocytopenia is a common toxic reaction of chemotherapeutic drugs, which may lead to dose reduction, delay or even termination of chemotherapy. Severe thrombocytopenia may cause bleeding and threaten patient's life. rhIL-11 and rhTPO are the only two drugs approved by China Food and Drug Administration for the treatment of chemotherapy-induced thrombocytopenia. The recommended dosage of rhTPO is 300U/kg. Clinical practice in the real world is full of changes and restraints. In the treatment of thrombocytopenia induced by chemotherapy, the actual dose of rhTPO is often below 300U/kg, due to factors such as Specs, economy and convenience. If the dose of rhTPO is insufficient, it can not give full play to the effect and thus can not achieve the purpose of rapid recovery of platelets. Previous clinical studies observed that the effect of rhTPO depends on the given dose. Dosage in the range of 75U-600U/kg of rhTPO were safe in human. While the 75U/kg dose group had no significant effect on the platelet count elevation, the platelet count in other three dose groups of 150U/kg, 300U/kg and 600U/kg increased by 24%, 32%, and 52% (P < 0.01). This research is a real-world study designed to verify the safety and efficacy of high-dose rhTPO in solid tumor patients with moderate or severe thrombocytopenia induced by chemotherapy. Patients with platelet count lower than 50 x 109/L will be enrolled and treated with high-dose rhTPO (300-600U/kg/day) until the platelets increased by 50 x 109/L compared to the baseline or above 100 x 109/L. During the study, the blood routine test will be regularly performed according to the clinical routine (at least once every two days) and the clinical data will be collected and analyzed. It is based on the patient's actual condition and the treatment measure is more consistent with the clinical practice. The results of this study are expected to provide new options and references for clinical treatment of thrombocytopenia induced by chemotherapy.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.
